Your Hamilton Insulation & Fireproofing Contractor

Hamilton's housing splits sharply along the escarpment — downtown brick rowhouses and west-end heritage, versus newer Stoney Creek and Ancaster subdivisions on the mountain. Northstar serves both sides, with crews running daily across the Linc and Red Hill.

Lower-city Hamilton homes often have stone or rubble foundations and old brick exteriors that need careful insulation — usually breathable cellulose in walls and closed-cell on rim joists. Mountain homes are typically newer and benefit from full spray foam packages.

Pre-1940 brick downtown and west-end housing, mid-century industrial-area homes, and newer mountain subdivisions.

Hamilton tip

Old brick Hamilton homes should never get spray foam directly on the back of brick — use dense-pack cellulose so the wall can dry inward.

Recent Hamilton project

Dense-pack cellulose wall retrofit on a 1912 Durand brick semi — kept original plaster intact, dropped winter gas bill 31%.
